Title: Stepped control method and device for height of air cushion
Inventor: ISHIKAWA RIYUUTAROU
IPC: B60G17/052
Filed: 1978-03-08
Abstract: PURPOSE:To provide a stepped control for the height of an air cushion in its balanced condition by constituting same such that an automatic height regulator valve adapted to admit air into the air cushion when the pressure of air in the air cushion is raised beyond a predetermined level has an operating lever whose fulcrum is lifted or lowered in a stepped manner. CONSTITUTION:As an air cushion 3 and a coil spring 3a are compressed by an increase of a load applied thereto from W0 to W1 with goods loaded thereto, a pushing up force of the coil spring 3a is increased and the pressure of air in the air cushion 3 is also raised, and a balance is reached at the height H1 of them. If the air pressure is over P1 then, a first valve 7 is opened so that the pressurized air is sent into a chamber C of a fulcrum shifting device 5 to push down a piston 51 to lower a fulcrum 0 to a height h2. Air in the air cushion is discharged depending upon whether the H1 is lower or higher than the height H2 of the air cushion corresponding to the h2, and when the H1 becomes equal to the H2, the air discharge is stopped. If the load applied is decreased, air is discharged from the chamber C through a second valve 8 and an exhaust port 83 to thereby restore the fulcrum to the initial position.
